- Single-sided FPC:
- basic flexible printed circuit board, composite of one layer of copper foil. This provides greater flexibility. In addition, it is lightweight, thin and space saving.
- Double-sided FPC:
- uses double-sided copper foil to provides greater flexibility, accommodates higher density wiring compared with single-sided FPC.
- Double access:
- has the same construction as single sided copper foil but opening at cover layer provides access to both sides of the copper layer.
- Multi-Layer FPC:
- a combination of single and/or double-sided flex circuits laminated with thermoset adhesive. Provides flexibility for complex wiring accommodated in limited space.
